Most Favorable Review

Purchased two with no regrets

TRENDnet TEW-633GR Wireless Router IEEE 802.3 (10Base-T) IEEE 802.3u (100Base-TX) IEEE 802.3ab (1000Base-T) IEEE 802.11b IEEE 802.11g IEEE 802.11n (draft 2.0)
TRENDnet TEW-633GR Wireless Router IEEE 802.3 (10Base-T) IEEE 802.3u (100Base-TX) IEEE 802.3ab (1000Base-T) IEEE 802.11b IEEE 802.11g IEEE 802.11n (draft 2.0)

Pros: I use one of these routers in each of my residences. Setup using a browser is very easy and the built-in help is very thorough. I have implemented many of its features, and neither router has ever been the cause of a lost connection.

Cons: I suspect that it is not the router, but rather the draft-N protocol, but I have never had a 300 Mbs connection. My standard connection is 130 Mbs. I have used three different wireless adapters: PCI bus, USB, and built-in to a laptop, and have actually placed the laptop next to the router to see if signal strength is the issue. It is not.

Overall Review: Do not install the network magic software that is included. It might not install correctly, and actually is more confusing than just using your browser.

Most Critical Review

Might not be adequate

Noctua NH-U9 TR4-SP3, Premium CPU cooler for AMD sTRX4/TR4/SP3 (92mm, Brown)
Noctua NH-U9 TR4-SP3, Premium CPU cooler for AMD sTRX4/TR4/SP3 (92mm, Brown)

Pros: Quiet, Easy to install if it fits.

Cons: Does not adequately cool a Threadripper 2 model 2950.

Overall Review: I installed an Asrock Taichi X399 motherboard with an AMD 2950 and 64 GB memory in an old case. I was concerned that the setup would be a tight fit, so I purchased this cooler, rather than the 14 inch version. It was a very tight fit, requiring that i move the fans up from the base in order to clear the RAM chips. Once i booted the system it was obvious that I had a problem because the CPU temp at idle was excessive. Running some test raised the temperature more. I looked at closed liquid cooling alternatives, None seemed much better in tests than the 14 inch Nactual cooler. (I have never played a computer game. The computer is primarily for scientific programming and phot processing of a very high res camera.) I decided to try the NH-U14S with a second fan. I only did so after I CAREFULLY COMPARED its dimensions and those of the motherboard. Amazingly, it fits better because it is narrower and higher. Equally importantly, the new cooler works better, with idle CPU temps below 40 deg and operational temperatures no higher than the mid 50s.

Beautiful but bad

LIAN LI PC-V2110A Silver Aluminum ATX Full Tower Computer Case
LIAN LI PC-V2110A Silver Aluminum ATX Full Tower Computer Case

Pros: I purchased this case because I liked its simple, yet elegant appearance, and it could accommodate all my components. I thought the front cover would make it quieter. I was wrong in that regard.

Cons: This was the third computer I built in the space of six months with essentially the same components. I used two to three 15k rpm serial scsi drives in a raid 0 for software, swap space, etc., combined with three SATA 7.2k drives in a raid 5. The vibration from them in this case produced an acceptable sound level. The problem is the way they are mounted. The side mount screws have rubber washers that are inadequate, and therefore transfer the vibration to the vertical metal plates that support the drive compartments. These plates are too flimsy, and vibrate themselves, which seems to be the source of the noise generation. I contemplated remanufacturing the case, but then decided to use it only occasionally for testing new software, and when I had a lot a number crunching. (All computers are used as engineering workstations, with no games.)

Overall Review: I know the noise is a fault of Lian-Li case for two reasons: (1) I did not have the problem with the same drive setup in an Antec P180, which was very crowded with all the drives, and a Thermaltake Armor MX, which looked somewhat geeky to me. (2) I sequentially pulled the drives but kept them connected. Sound levels progressively went down. As an aside, the Lian-Li was the most difficult to assemble. In particular, there is a fan that is claimed to cool the graphics card. It mounts on an internal post, but you need to be a contortionist, or have a set of forceps, or have an assistant to mount it. Also, this case gives the highest temperatures for the CPU (quad Pentium at 2.8 GHz). I installed an extra 120 mm fan in three 5 1/4 in drive bays as an intake, which helped. The Armor case has two quad Zeon processors at 2.8 GHz, and its temperatures at all locations are lower.) Bottom line: Do not buy this case!

Good board but BIOS needs work

SUPERMICRO MBD-X7DWA-N Extended ATX Server Motherboard Dual LGA 771 Intel 5400 DDR2 800
SUPERMICRO MBD-X7DWA-N Extended ATX Server Motherboard Dual LGA 771 Intel 5400 DDR2 800

Pros: This board has many features, all of which work the first time. I am using another manufactures serial scsi, which controls two drives and a DVD-RW, but having six usable SATA slots is great. I use three for a 3 drive RAID, one for another DVD-RW, and one for an external SATA backup.

Cons: Two problems with the Phoenix BIOS: (1) It only shows four SATA slots in setup, and does not indicate that anything is connected in those slots. Fortunately this is irrelevant since the RAID configuration works. (2) There is no provision for changing the set points for alarms. Specifically, the motherboard is set to trigger an alarm at 50 deg C, which I think is well below what actually would be harmful. The highest temperature I have seen is 48 deg C, which is too close for my own comfort, As of Feb 10, there was no update to the BIOS at the Supermicro site.

Best case I ever used

Thermaltake ArmorPlus(Armor+) VH6000SWA Silver Aluminum ATX Full Tower Computer Case

Pros: The construction quality is the best I have seen. (This is probably the sixth computer I have built.) Everything from the tool less installation (you do need a screw driver to mount a floppy drive in a tray) to the removable motherboard tray to the arrangement of the drive boxes has been well thought out. Ventilation is very good.

Cons: The front doors do not cover much, and offer no barrier to sound that propagate through the mesh slot covers. The power button is situated on the top front, where it can be pressed accidentally. The smaller fans seem to be noiser than other I have used, and I will replace them soon.

Overall Review: I do not like clear plastic side covers, so I painted the inside with metallic silver paint, and the I like the effect. Also, I covered any bare areas inside the case with aooustical liner (1/4 inch polymer foam), which serves to absorb some noise, but I do not know how much since I did it before installing the motherboad.

Works well but too big

SAPPHIRE Ultimate Edition Radeon HD 3850 512MB GDDR3 PCI Express 2.0 x16 CrossFireX Support Graphics Card 100226U
SAPPHIRE Ultimate Edition Radeon HD 3850 512MB GDDR3 PCI Express 2.0 x16 CrossFireX Support Graphics Card 100226U

Pros: Quiet, yet cool. Seems to be fast, but I do not play games so I cannot vouch for its speed.

Cons: This card obviously needs two slots, but I did not realize that the the extra width is on the side of the board opposite where the processor is. It fit fine in the case but was blocked by the one of the processor (Supermicro board with dual Xeon 5440). I moved it to a computer with a single Pentium quad processor, and have had no additional problems.
